Is it normal to sometimes accidentally use the wrong tone of voice?

Do most people sometimes (or at least on rare occasion) say something in a tone of voice that they didn't intend?

Example: You are feeling happy and try to say something loud, it comes out sounding irritated (possibly because of the strain to your vocal cords), even though you don't feel that way and didn't intend it to sound that way.

IMO, this reflects badly on a person even if it happens rarely. Let's say it happened in front of a group of coworkers and supervisors you are just getting to know. What can be done? (I think it might be best to just let it go and try to be more self aware next time.)

I had that happen once and still feel bad about it! I was trying to say something in a teasing tone, but it came out wrong and the person thought that I was angry. It was at work.

In hindsight, I wish I had explained the mistake immediately and apologized for the way it came out. I actually think the comment had a lasting negative impact on my relationship with that coworker.

I do it all time. It gets me trouble.

I don't think we can wholly plan tone of voice or how another will perceive it and know it is not all that goes into how someone interprets what we say so I think it is dangerous to "try" for a particular tone. We may also think we are "teasing" when we are angry and don't want to be perceived as angry but it become obvious because our words are not the kind that lend themselves well to "just" teasing (so at best we come across as passive aggressive). I do not consider "loud" a tone and I know I "irritate" my husband daily because I am hard of hearing and often say things too loud and it does not matter what I am saying.

I think I would just accept if what I was trying did not "work" and apologize and explain what I meant and then move on. I would not bother wasting time on continued remorse or worry about if people thought poorly of me, etc., nothing I can do but apologize and move on, leave it up to them to accept my apology and realize I meant no harm or hold it against me, whatever their personal bent might be. My words can only suggest things, not make others believe/change/do something how I'd like.

I agree with most of this.

Now, if it's not feasible to apologize or correct oneself in the moment, I'm thinking there may be opportunities in the future to do something about it, even if those coworkers are not people you normally talk to. This is going to boil down to social skills.

My sarcasm or jest tends to get lost for this reason. Then I have to explain myself and sound like a nerd. Geekiness is cool this days so it tends to work out.

Same here.

It's also my eyes and eyebrows. They say I have "angry eyes." I don't mean to look and sound mad or irritated but I suppose it comes off that way sometimes.

I try to compensate by telling jokes a lot, laughing and smiling a lot more. It's sort of become a habit. I try to find something funny all the time.

It seems to be working because a lot of new acquaintances describe me as "jolly." Haha

Sometimes tho, especially at work, I can't help but look and sound irritated/mad, because I genuinely am. But I always try to not end things there. I always try to move toward something constructive and I try to end the meeting with us smiling or better yet laughing. Unless of course there was real malice or bad intentions involved, then I give them the death stare so to speak.
